 # CodeView (Android)
 CodeView helps to show code content with syntax highlighting in native way.
+
+## Description
+CodeView contains 3 core parts to implement necessary logic:<br>
+1. <b>CodeClassifier</b> is trying to define what language presented in code snippet. It built upon <a href="https://github.com/ptnplanet/Java-Naive-Bayes-Classifier">Naive Bayes classifier</a>. There is no need to work with this class directly & you must just follow instructions below.<br>
+2. For highlighting it uses <b>CodeHighlighter</b>, just highlights your code & returns formatted content. It based on Google Prettify and <a href="https://github.com/twalcari/java-prettify">their fork</a>.<br>
+3. <b>CodeView</b> & necessary adapter.<br>
+
+## Download
+Add it in your root ```build.gradle``` at the end of repositories:
+```groovy
+allprojects {
+	repositories {
+		...
+		maven { url "https://jitpack.io" }
+	}
+}
+```
+
+Add the dependency:
+```groovy
+compile 'com.github.softwee:codeview-android:1.0.0'
+```
+
+## Usage
+If you want to use code classifier to auto language recognizing just add to your ```Application.java```:
+```java
+// train classifier on app start
+CodeProcessor.init(this);
+```
+
+Add view for your layout:
+```xml
+<io.github.kbiakov.codeview.CodeView
+        android:id="@+id/code_view"
+        android:layout_width="wrap_content"
+        android:layout_height="wrap_content"/>
+```
+
+Use chaining syntax when build view:
+```java
+CodeView codeView = (CodeView) findViewById(R.id.code_view);
+
+codeView.highlightCode("js")
+        .setColorTheme(ColorTheme.SOLARIZED_LIGHT.withBgContent(myColor))
+        .setCodeContent(getString(R.string.listing_js));
+```
+
+And perform actions sequentially when view built:
+```java
+codeView.setCodeContent(getString(R.string.listing_java));
+codeView.highlightCode("java");
+```
+
+You can use both forms for build & built view, but note: ```setCodeContent(String)``` is final step when you build your view, otherwise not. If you firstly highlight and then set code content, code will not be highlighted. Instructions above helps you to avoid errors. View has state to handle this behavior.
+
+## Customizing
+1. Use implicit or eplixit form to code highlighting:
+```java
+codeView.highlightCode();
+```
+```java
+codeView.highlightCode("js"); // it will work fast!
+```
+
+2. Extend default color theme or create your own (don't forget to open PR with this stuff!):
+```java
+int myColor = ContextCompat.getColor(this, R.color.code_content_background);
+codeView.setColorTheme(ColorTheme.SOLARIZED_LIGHT.withBgContent(myColor));
+```
+```java
+codeView.setColorTheme(new ColorThemeData(new SyntaxColors(...)));
+```
+
+3. Handle user clicks on code lines:
+```java
+codeView.setCodeListener(new OnCodeLineClickListener() {
+    @Override
+    public void onCodeLineClicked(int n) {
+      // your logic here
+    }
+});
+```
